概括

这项研究发现,NIH工具箱认知电池 (NIHTB-CB) 上的流体认知得分的个体内变异性在人口统计学方面显示出小差异,但缺乏测试-重新测试可靠性. 对于这些分散分数,需要进一步的心理测量研究.

科学领域:

认知心理学认知心理学
心理测量心理测量心理测量
神经科学是一个神经科学.

背景情况:

对于理解认知健康而言,认知表现的个体内变化 (IIV) 是至关重要的.
美国国立卫生院工具箱认知电池 (NIHTB-CB) 是评估认知功能的广泛使用的工具.
在NIHTB-CB内对IIV测量的心理特征进行的研究有限.

研究的目的:

通过使用NIHTB-CB.CB来检查流体认知测试成绩的个体内变异性 (IIV).
在各种社会人口统计特征中比较IIV.
为了估计IIV分散分数的测试-重新测试可靠性.

主要方法:

参与者 (N=730) 完成了NIHTB-CB,一个子样本 (n=138) 在1-2周内完成了重新测试.
流体认知得分被转换为年龄调整的标准得分和人口调整的T-得分.
计算了个体内标准偏差 (ISD) 和个体内变化系数 (ICV) 来量化IIV;使用类内相关系数 (ICC) 评估了测试复试可靠性.

主要成果:

在种族/种族,性别和结晶的认知得分之间观察到IIV (ICV,ISD) 的轻微显著差异,但效果大小很小.
对ISD的试验-重试可靠性很差 (ICC=0.33-0.49).
对ICV的测试-再测试可靠性差到中等 (ICC=0.43-0.63).

结论:

在NIHTB-CB流体认知得分中的IIV在社会人口统计学群体之间没有实质性的差异.
两种IIV的ISD和ICV测量都在短时间的重新测试间隔中表现出不良到中度的稳定性.
需要进行额外的心理测量研究,以验证IIV分散得分在研究和临床实践中的使用.

Self-Report Tests of Personality

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Behrens–Fisher Test

Behrens–Fisher Test

The Behrens-Fisher test is a statistical method designed to address the Behrens-Fisher problem, which arises when comparing the means of two normally distributed populations with unequal variances. Unlike the Student's t-test, which assumes equal variances, the Behrens-Fisher test allows for mean comparison without this restrictive assumption. This flexibility makes it particularly valuable in scenarios where two independent samples exhibit normality but lack variance homogeneity.

Stereotypes, Prejudice, and Discrimination

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...
